Cell Handler Acceptance Test

The first thing we're going to do is use the cell handler inspector to retrieve the current list of cell handlers.

Next, let's clear the list.

And look at it again

Now, we'll put the defaults back

And, presto! They've reappeared!

Let's load an optional module

And it appears in the list

Let's get rid of one

And it's gone

Now let's try loading something that doesn't exist.

And it wasn't loaded
